KLKB1
KLKB1，全稱為Kallikrein B1，也被稱為PKK、PPK、KLK3、PKKD。該蛋白參與血液凝固、纖維蛋白溶解、激肽生成和炎癥等過程。KLKB1與高分子量激肽原形成復合物，在凝血因子XII的激活下，將前原蛋白轉化為激肽釋放酶，進而生成緩激肽。緩激肽參與血管通透性的調節、炎癥反應以及內源性凝血和纖溶過程。KLKB1蛋白的突變會導致前激肽原缺乏，引發遺傳性血管性水腫（HAE）。HAE是一種罕見的遺傳性疾病，患者體內缺乏C1酯酶抑制物或其功能存在缺陷，導致皮膚和黏膜反復發生水腫。針對KLKB1的藥物研發主要集中在HAE的治療上。例如，KalVista公司開發的口服血漿激肽釋放酶（KLKB1）抑制劑Sebetralstat已獲得歐洲EMA的上市授權申請，用于按需治療HAE。此外，Rezolute公司的小分子KLKB1抑制劑RZ402也在臨床試驗中顯示出良好的療效，用于治療糖尿病性黃斑水腫。這些藥物的研發為KLKB1相關疾病的治療提供了新的選擇。

(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
KLKB1 Recombinant Monoclonal Antibody (CSB-RA553053A0HU)
驗證數據
IHC image of CSB-RA553053A0HU diluted at 1:100 and staining in paraffin-embedded human liver tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.
